Direct bolt on Mazdaspeed - Billet wheel TD05H-20G Turbo

Some time ago I pursued a direct bolt on turbo using Mitsubishi turbo center sections for the speed 3 & 6. My initial work did not have any success due to having to lay out more than I could afford to invest upfront. Recently however I have had some back and forth with manufacturers and have finally some exciting news to share.

I am not responsible for the design of this particular turbo, but I am hopefully going to be bringing it to the us market.

On the way is a direct bolt on turbocharger for the speed 3 & 6. Using a td05h turbine wheel with a light weight 9 blade design & a 20g extended tip billet compressor wheel. The turbo also has a billet waste gate actuator that can have different springs swapped into it.

I have a test unit in shipping right now and will update you guys soon.

The main goal of my testing for this turbo will be fitment / ease of installation, as well as to see what kind of power it will make.

I won't focus on testing durability, because the center section is a proven component from a respected company so durability isn't going to be a problem.

If this turbo bolts in properly and performs, then Adapted Performance will be bringing them to the market for you guys.

Pricing should be under $1000 delivered to your door with a 1 year industry standard warranty.

Pictures and details to follow.

 

The corkport is comprable to an 18g right? Just trying to figure out where this slots in size wise.

 

As far as I know the corksport is an 18g

 

Definitely interested. Dose this take from any of your past work, or a new design.

 

No, nothing from my work before. That is a project that I pretty much gave up hope on. But oddly enough a manufacturer I contacted several years ago about this project developed the turbine and compressor housings to make this a reality.

I have a strong feeling that the design of this turbo was influenced by a well placed series of emails from a few years back, I repeatedly emailed letting them know the demand was high. I honestly don't know the story other than when I contacted the same manufacturer they replied that they have turbos now.

I am excited to get the sample turbo in hand and check it out & get you guys pictures.

 

This could be a good addition to the platform, while I'm not sure where my turbo goals are currently (dream vs reality) I'm looking forwad to where this goes

 

Definitely interested in more information.

 

In typical(for me) Mitsu turbo fashion, the manufacturer of this turbo contacted me to say they had issues with machining the compressor casting to accept the 20g wheel. The inlet was too thin using the stock 2" inlet diameter.

Which added a bit of confusion because I thought they had turbos ready to ship out. They said they can machine a raw casting with a 2.2" inlet size and the 20g wheel should be doable, or throw on an off the shelf 20G compressor cover which will leave more fab work. I am waiting on seeing what they can do to make the 20g work.

They have off the shelf 18G turbos ready to send out right now though.

These are from Kinugawa turbo

 

So how would these turbos compare to the S3 and CS in terms of boost threshold, spool time, transient response, and flow rate? With a great flowing setup, what whp #s could we reasonably be looking at (assuming sufficient fueling)?

 

Well, the 9 blade turbine / billet 18g will be exactly the same as CS - I can explain more via PM

A 20g wheel version I was hoping would compare more with the BNR S3

 

So @Adapted_Performance has there been any testing/news for this?

 

Supposed to be ready next month or 2

 

Any updates?

 

Excited for info on this. Bought an s4 already and I'm sure these won't compete with that but this is still interesting.

 

Yeah, it's not even close. This Kinugawa has a ~50/60mm compressor wheel; the BNR S3 has a ~53/71mm compressor wheel. In other words, even the S3 should flow a LOT more air.

 

Pretty sure the turbo pictured is not the turbo he intends to sell. Kinugawa does make some cool stuff for the k04 chra, though.

 

Yes, I agree. I was talking about the comparison between the Kinugawa and the CS. Comments about how it compared to BNRs also arose, so I just shared the S3 wheel measurements.

 

I kind of got tired of the run around dealing with them.

They say they can do one thing and then are only willing to do it if I pay a mold fee, etc, etc. I may strike up a conversation with them again soon.

You can get the td05h / 18g from them currently.

Supposedly there is enough meat on the turbine housing to machine it to accept a larger td06sl2 turbine wheel.

I feel a td06sl2 / 60-1 hybrid combo coming soon.

I have a turbine housing here but have yet to do anything with it.

May have more time this winter to play with it.

 

But if we could do a 20g compressor wheel or even a 60-1 hybrid, heck even a 25g would be cool, but not with the small td05h turbine wheel.

 

Sure, but I'm not sure how you're going to attach the mitsu CHRA to the housing. The inducer of the turbine wheel is the limiting factor. I was just machining a K04 exhaust housing to fit this 46.5/52 turbine wheel. There was barely enough material on the inducer side to maintain the all surfaces of the V-band type seal. A 61mm inducer would definitely be an issue. On the other hand, the exducer has plenty of material and room to grow.

Re: keeping the stock compressor housing- you could keep the stock 2" intake, if you could find a wheel with a large exducer and a ~50mm inducer. I.E. Turbolabs sells a 50/65 compressor wheel for use with the stock CHRA, and there's room for more exducer in the stock housing- but the trim will fall.
